Review of Topics in Physics 1

I have now finished the first half of the grade 12 physics course in the Ron Paul Curriculum. This past week was spent reviewing the topics and concepts that were taught from Week 3 to Week 17. Throughout each week I worked through practice problems, and though I wanted to type them out here, they were far too complicated for my keyboard.

Week 3:

  • Position
  • Motion is relative
  • Change in position: velocity and speed
  • Change in velocity with respect to time: acceleration – slope of the curve or line
  • Gravity on earth: 9.81 m/s^2
  • Relating velocity and displacement: change in V = a * t
  • Unit conversions
  • Kinematics: position, velocity, and acceleration
  • Constant acceleration
  • Kinematic equations
    • v = v. + at
    • v = (v. +v)/2
    • x = x. + v.t + ½ at^2
    • v^2 = v.^2 + 2a(x – x.)

Week 4 & 5:

  • Practice problems

Week 6:

  • Forces
  • Newton’s 1st law of motion
